Georgetown Cupcake Founders Share the Perks of Running a Family Business

They left behind their stable careers for cupcakes.

“When we started it was 2008, no banks were lending at all,” LaMontagne tells ABC News' Rebecca Jarvis. “They say that sometimes the best business ideas die in bank parking lots because if you don’t have the money, people keep telling you no, so we had to find a way to get to yes.”

Now, there are six Georgetown Cupcake locations around the country and a TLC “cupcake cam” with 24/7 live feeds of their flagship DC bakery location. The sisters also are best-selling authors of "The Cupcake Diaries" and "Sweet Celebrations."

When the sisters sat down with Rebecca Jarvis for an episode of Real Biz with Rebecca Jarvis, they shared one of their secret ingredients to success: family.

“Being sisters has actually helped us, we don’t sort of tip-toe around each other,” said Berman. “If Sophie doesn’t like something she tells me to my face, she doesn’t sugar coat it. I think we’re able to make the best decisions for our company by just hashing it out.”

With only a year-and-a-half age difference between them, the Kallinis sisters were always close. They spent their afternoons baking with their Greek grandmother, who lived down the street from their Toronto house and taught them traditional Greek recipes from scratch. That family tradition has now carried on with their mother, who has stayed on as an employee since the store opened.

“It was just the two of us, and our mom came to help us for the weekend and she ended up never leaving,” Berman said.

“I think that it’s important when you choose a business partner to make sure that your relationship can withstand it, and family businesses can go either way,” LaMontagne said. “There are going to be highs and lows in a business – nothing goes straight to heaven. It’s going to be a roller coaster.”
